Honoring Dr. David Sackett, father of evidence-based-medicine

Dr. Last week Dr. David Sackett, considered by many to be the father of evidenced-based medicine, passed away. He founded the first department of clinical epidemiology and biostatistics in the world at McMaster University, Ontario in 1967 and established the Centre for Evidence-Based Medicine in the UK in 1994.

In honor of Dr. Sackett’s tremendous impact on evidence-based practice, we are sharing a small sample of citations to articles and books from the Hardin Library collection below.

5 million downloads

We are very excited to have had 5 million downloads in Iowa Research Online! We had 4 million downloads in November, so this last million happened in only about 6 months. Some of this growth is attributable to the fantastic content added recently (such as the State Historical Society journal Annals of Iowa, back to 1863).

I Hear the Train a Comin’

Hallidie U.S. Patent 110,971For more than two centuries, trains have traversed the American landscape altering how and where people live and work. This is why, in 2008, Amtrak created National Train Day to be celebrated on the Saturday closet to May 10th, the anniversary of the pounding of the Golden Spike in Promontory, Utah which marked the completion of the First Transcontinental Railroad.

The first locomotive was built in 1804 by a Cornish inventor named Richard Trevithick. It was powered by steam. A steam locomotive burns fuel, usually coal. The heat then passes though tubes inside a large water-filled boiler creating steam. The steam then passes through high-pressure tubes to cylinders which engage piston rods connected to the locomotive’s wheels, thus driving the train.1

The steam engine remained popular until the early 1900s when diesel and electric began replacing it. A German mechanical engineer, Rudolf Diesel, invented the diesel-powered locomotive. A diesel engine operates when a cylinder piston squeezes and heats air trapped inside; at the top of the stroke, the system injects oil; the air and oil mixture burns and drives the piston down which turns a crankshaft connected to a generator making eletricity for storage in large batteries. The wheels are powered by motors that draw from the batteries. 2

On January 17, 1871, Andrew Smith Hallidie, an American engineer and inventor, was granted a patent for an “improvement in endless wire ropeways” which became the basis for the first cable car system.3 Soon, however, electricity changed city transportation. In 1897, Boston opened an electric subway system. New York City soon followed in 1904. The all-electric locomotive requires either an overhead pickup or a third-rail carrying a high-voltage of electricity to power the engine. Electric trains are easier and cheaper to maintain and last longer than diesels.4

Now coming down the track are hybrid trains which use a battery to store energy temporarily for when the train is idling or stationary; “bullet trains” which run on steel rails at accelerated speeds; magnetic levitation trains which hover above rails suspended by powerful magnets; and the futuristic Hyperloop, Elon Musk’s vision for transporting people in high speed capsules through a series of tubes.

The world’s fastest passenger train, the Maglev, owned by the Central Japan Railway Company, made history last month by hitting a top speed of 366 mph surpassing its previous record of 361 mph set in 2003.

The Federal Railroad Administration was created by the Department of Transportation Act of 1966. The U.S. agency regulates the manufacturing and safety of the train transportation industry. A few of the more widely known train manufacturers are National Railway Equipment Company (NREX) headquarted in Mt. Vernon, IL. This company is known for its N-ViroMotive engine which is used for light duty road switching in yards and urban areas where noise and exhaust emissions are to be reduced. GE Transportation Systems (GETS), a division of General Electric, is headquartered in Chicago while its main manufacturing plant is located in Erie, Pennsylvania. This company is the largest producer of diesel-electric locomotives. Its Dash9 series has an electronic fuel injector and a 4-stroke diesel engine.

Gomaco Trolley Company, located in Ida Grove, Iowa, manufactures trolley cars which look vintage but have state-of-the-art technology. Streetcars or cable cars are used in cities such as Portland, San Diego, San Francisco. Rapid transit commuter trains, known as the metro or subway, are a primary means of transportation in Atlanta, Washington D.C., and New York. U.S. Manufacture of Rail Vehicles for Intercity Passenger Rail and Urban Transit documents several companies which manufacture parts for high-speed, rapid transportation.

We expect to start on our march to Washington in the morning

Joseph Culver Letter, April 29, 1865, Page 1

Hd. Qurs. Co. “A” 129th Reg. Ills. Vol. Infty.
Raleigh, N.C., April 29th 1865
My Dear Wife

We expect to start on our march to Washington in the morning at 5 o’clock, & though the last mail went out for the Corps, yet I will try & mail this in the 23d Corps which is to remain here for the present.1 It is raining to-night & bids fair to be a wet day to-morrow. I was in hope that we would rest until Monday morning [May 1], but, though we do not see it, doubtless the necessity exists for our immediate departure.

We are in good health & all ready for this our last campaign. The cannon have been booming at intervals of 30 minutes throughout the day, & all Officers of the Army assume the badge of mourning for 6 months. We have not yet learned the particulars of the negotiations. Many vague rumors are afloat, but we must wait until we get through to the north for more definite information.

Chris [Yetter] has not been well for a couple of days, but I think it is only a slight cold. Nate [Hill] has had headache for two days. Allen Fellows in playing with Billy Perry this evening received a severe cut in his hand from a knife Perry was whetting.2 His hand is doing quite well to-night, & I think will be well in a few days. I saw Bro. John Lee this evening at Church. We had a good meeting.

We were inspected & mustered to-day; only once more, & we hope to be done. Every day & every hour of the day, you may hear the boys talking of “Home Sweet Home.” I have been so busily engaged with papers that I could not enter into their enjoyment as much as I would like.

By the time this reaches you, we will be doubtless at Richmond, Va., or beyond it. I hope to receive several letters from you there. I would like very much if our house could be vacated so that we might go immediately to housekeeping on my return, yet I can give no definite idea of the time we will reach home. If convenient for Mr. Mathis, ask him to leave by the 1st of June.

It is getting quite windy, & the light will not last much longer, so I will close. Remember me kindly to all our friends. Tell Maggie Gutherie that I did not get time to answer her letter here. Kiss Howard for me. May the richest of Heaven’s blessings rest upon you & preserve us for future enjoyment in this life. With much love, I remain, Ever,

Your affect. Husband

  1. General Grant, on the 29th, wired Washington that four corps would march from Raleigh to Alexandria, passing near Richmond. General Mower, during the day, informed his XX Corps that they would “commence the march to-morrow.” The First Division would take the lead, followed by the Second and Third. Mower hoped the march would be so regulated that the corps would be across the Neuse when it halted for the night. O. R., Ser. I, Vol. XLVII, pt. III, pp. 345, 348.
  2. William W. Perry, a 20-year-old drayman, was mustered into service on Sept. 8, 1862, as a private in Company A, 129th Illinois Infantry. Private Perry was detailed as regimental ambulance driver on Dec. 2, 1862, and did not rejoin the company until May 5, 1864. On Aug. 28, 1864, he was detailed for duty in the regimental medical department, where he remained until mustered out on June 8, 1865, near Washington, D.C.
